6.4 Two channel, switching and dimming with slave control
Switches the relay channels with occupancy and provides dimming control for DSI/DALI enabled
luminaires; with multiple connection to slave sensors.
Wire the system as in the diagram below. The master sensor provides the dimming signal. The voltage-
free output contact from multiple slave sensors is connected to the slave input of the master sensor.
This configuration is particularly useful for systems where the dimming fittings never turn off but provide a
minimum level of illuminance when the area is un-occupied (generally for safety reasons). DSI/DALI does
not allow multiple masters to generate the dimming signal, hence the use of one master and multiple
slaves. It is important in this configuration that the slave sensors are
not
connected to the DSI/DALI bus.
In this configuration it is recommended that the relays are disabled on the master using the jumpers.
